ASDA-A3
The Speed command selection is determined by SPD0 and SPD1. See the following table.
Speed DI signal of CN1

0: means that DI is off (the circuit is open).
1: means that DI is on (the circuit is closed).
The parameter setting range of the internal register is from -75000 to +75000.
Rotation speed = setting value x unit (0.1 rpm).
For example, P1.009 = +30000, and the rotation speed = +30000 x 0.1 rpm = +3000 rpm.
Command setting for the speed register:
Set P1.009 to +30000.
Set P1.010 to +1000.
Set P1.011 to -30000.

Step 3:
(a) Switch on DI1 and the drive is in the Servo On state.
(b) When both DI3 (SPD0) and DI4 (SPD1) are off, that means the drive executes the S1
command. The motor rotates according to analog voltage command.
(c) When DI3 (SPD0) is on, that means the drive executes the S2 command. The rotation
speed is 3,000 rpm.
(d) When DI4 (SPD1) is on, that means the drive executes the S3 command. The rotation
speed is 100 rpm.
(e) When both DI3 (SPD0) and DI4 (SPD1) are on, that means the drive executes the S4
command. The rotation speed is -3,000 rpm.
You can repeatedly execute steps (c), (d), and (e).
(f)
(g) If you want to stop the motor, switch off DI1 (Servo Off).
